Study on Mechanical Behavior of Webs of Abrea Bridge
Bao Lin Pan, Jun Liao · Applied Mechanics and Materials · 2013
PC box girder bridges with open-work webs, mechanical behaviour of which is half way between those of traditional plain web and lattice box girder, is a kind of new bridge form. As webs are not continuous, vertical force cannot travel by shearing effect in a classic way all along the deck, so the hollow web box girder designed bridge behaves very differently compared to usual plain web box girder bridges. In this paper, mechanical behavior of webs of Abrea Bridge in France was analyzed by using Ansys tool. PC box girder bridges with open-work webs have many good features such as artistic and economic, etc. It can be studied and applied further in the world.
